How to drain radiator...94 E320?

[WhyNot]

Appreciate advice as to whether there is a drain-petcock on the radiator of a 94 E320? If not how do you drain and flush in order to replace coolant? Thanks.

Thanks Joey...appreciate the quick repsonse. Is the block-petcock fairly easy to locate. I assume it's advisable to drain from both locations, radiator and block...true?
